Individuals' steadiness of mood, their ability to withstand
minor setbacks, failures, difficulties, and other stresses without becoming
upset emotionally. Emotionally stable persons tolerate minor stresses
and strains of day to day living without becoming emotionally upset, anxious,
nervous, tense, or angry. They are able to maintain composure under minor
emotional stress. They are fairly constant in their basic mood, and they
generally revert quickly to that state following those occasions when
they have experienced considerable stress or have been exceptionally provoked.
The unstable person, on the other hand, is subject to fairly wide, frequent,
and often unpredictable mood shifts that may swing from pole to pole.
Emotional stability is an important and useful state of being. With
emotions managed and under control, yet still having the ability to feel
intense emotion and understand the reason for the emotions, a power in
situations is gained.
